Siemens 6ES7417-5HT06-0AB0 SIMATIC S7-400H CPU 417-5H PN/DP 32MB Fault-Tolerant Programmable Logic Controller

The Siemens 6ES7417-5HT06-0AB0 is a SIMATIC S7-400H CPU 417-5H PN/DP central processing unit for S7-400H and S7-400F/FH fault-tolerant systems, with 32 MB of work memory (16 MB program, 16 MB data) and 5 interfaces: MPI/DP, DP, PROFINET, and 2 ports for synchronization modules. It connects up to 119 operator panels.

Technical Specifications

Selection Notes

Compared with the 16 MB CPU 416-5H PN/DP in the same H-series line, this CPU doubles work memory to 32 MB, split evenly 16 MB program / 16 MB data rather than the 416-5H's data-heavy 10/6 split, which favors larger control programs over large data sets. The same 2 synchronization-module ports link a redundant CPU pair or support fail-safe operation. Where 32 MB of memory is more than a process needs, the 416-5H PN/DP covers the same redundant/fail-safe role at lower memory cost.

Applications

Large fault-tolerant and safety-related S7-400H/F/FH process control programs that need 32 MB of work memory across a redundant CPU pair with PROFINET IO and PROFIBUS DP I/O.
